±1500kV特高压直流输电技术前期研究
Development of Technologies in ±1500 kV UHV DC Transmission Research
摘要
Abstract
With the proposed "The Belt and Road" strategy,a large number of multinational networking and cross-regional networking will be needed in the development of power grid in the future.In the meantime,since the area of power transmission corridor will also be an important factor to restrict the development of power grid,the UHV DC transmission lines with higher voltage levels are also needed to reduce line corridors dramatically.It is urgent to carry out the early research of UHV DC technology with higher voltage levels because of these two aspects.On the basis of ±800 kV and ±1100 kV DC transmission technology,we research the key technical challenges in main electric connection design,overvoltage and insulation coordination,external insulation characteristics,electromagnetic environment,and lightning protection with the voltage of ±1500 kV so as to provide technical supports for future selection of higher voltage levels.UHV DC transmission technology with the voltage higher than ±1100 kV is an important development of long-distance and large-capacity power transmission technology in the world,which can optimize the energy allocation in larger area compared to ±1100 kV DC transmission technology.关键词
